ATTACHMENT FOR THRED-TEVISTNG l/IACHINES,

Be it known that FRANK M. Roenes, a citizen ot the United States, residing at Baltimore, in the State ol Maryland, has invented certain new and useful lmproveinents in Attachments for Thread-Twisting Machines, of which the following is a specication.

Plhis invention relates to an attachment for thread twisting machines and is especially directed to an oil catcher device for attachment to the guide-tubes or spindles of such machines whereby any oil that may ilow down such tube or spindle may be caught and the same prevented from fouling the entrance to such tube or spindle where it would be wiped oil" by and stain the strands entering the tube and which are to be twisted together into a single thread.

The invention is illustrated in the accompanying drawing, wherein,-

Fig. 1 shows a portion of a thread twisting machine including a guide-tube to which one form of my improved oil-catcher is attached.

Fig. 2 illustrates an enlarged vertical secitional detail through one of the guide-tubes and the oil-catcher, and

Fig. 3 shows a horizontal sectional detail through the oil catcher' and guide-tube,- the section being taken on the line 3-8 of Fig. 2.

Reerring to the drawing the numeral 5 designates a portion of the framework forming part of a well-known Jform of thread-twisting machine and including a horizontal cross-bar 6.

A shaft 7 is suitably sustained by the trame and carries a beveled pinion 8 which latter meshes with and drives a bevel gear 9, shown in broken lines in Fig. 1.

The gear 9 carries a vertical tube 10 which latter is rotated to etlect the twisting-together of the several strands which are combined to form the completed thread 23.

Beneath the cross-bar 6 there is provided, in this instance, a bracket 11 which latter sustains one orm of a vertical guide-tube or spindle 12 in vertical alinernent with the rotating tube 10 ,-the lower end of the rotating tube extending down below the gear 9 and terminating at the upper end of the guide-tube or spindle, as shown in Fig. 2.

The guide tubes or spindles 12 may, in some forms et twisting machines, be revolved., while in others, they may remain stationary, and it is immaterial to the present invention whether such tubes revolve or not.

At the lower end of the guide-tube or spindle 12, in the 'form shown, there is a sleeve 13 with a nipple-like plug 14 in its lower end which nipple has a tapered central passage 15 with a flaring entrance 16, so that t-he several strands of threads to be twisted together may enter the nipple-passage from any point around the circumference thereof without cutting the libres as they are drawn therein and be directe-d into the tube above it.

ln machines of this character itis common to provide carriers or tables 17, on which a series of spools or bcbbins 18 of thread 19 are mounted and a strand from each of the spools is led into the tapered guide passage o the nipple from which it passes up through the spindle or guide-tube to the twisting means.

Because of the comparative high speed ot the twisting device in these machines, it is necessary to thoroughly lubricate the parts and it is a common thing for the lubricant to flow down the spindles or guide tubes to the thread-entrance where the oil will come. in contact with and be wiped o by the entering strands 19 and the latter thus become stained. To prevent this staining oim the strands I provide an annular basin or cup 20 to catch and collect the oil. These basins or cups are, in the present illustration, shown as formed integrally with the spindles or guide-tubes and thereby avoid attachments or oints through which oil might leak, but this particular forni and arrangement of cup is not essential.

ln the present instance it will be noted that the basins or cups have an inwardlycurved upper edge 21 and a pad 22 is pro- ;vided in the bottom thereof.

The inwardly-curved upper edge 21 is especially desirable in spindles or tubes which are revolved because, by thus contracting the wall at the tnp, any oil conned in the delivering a series of thread strands to the Y guide7 means for twisting the strands together and a basin closely fitting the exterior of the tubular guide above the entrance of the thread strands.

2. In a thread twisting machine the combination with a. tubular guide, of means for delivering a series ot thread strands to the guide, means for twisting the strands to-` gether and a basin carried by the tubular 1 ,season guide and extending around the exterior of the latter said basin having an inwardly-ex tending wall near its upper open edge.

3. In a thread twisting machine the combination with a tubular structure through which the thread strands to be twisted together pass, means for twisting the strands together and a basin associated with the tubular structure to catch any oil owine along the exterior thereof to prevent the said oil from staining the strands entering the tubular structure.

LI. In a thread twisting machine the combination with a tubular guide, of means for delivering a series'of thread strands to the guide, means` for twisting the strands together, anannular basin formed Von the: eX- terior of the tubular guide and extending around the latter and open at its upper side, and a pad on the interior of the basin.

In testimony whereof I atrix my signature; i
